Some of us still run conventional in old vehicles because we don't believe in tempting fate with the seals / esters if its not leaking is a grand idea. Its lasted this long without leaking, why tempt fate.Just did a search on Walmarts app for “10w-40” and the Mobil 1 High Mileage 10w40 is only $7 more per jug than the other name brand synth blends. $7 an OCI is the difference of an extra coffee over the course of an OCI. I’d just spring for the Mobil 1 High Mileage and call it a day if it were me.
Who am I kidding? If it really were me, this would be my choice.
